Link demonstration

This section describes the steps required to set up a quick demonstration that
will enable you to send text from one PC to another PC using a wireless link at
32 kbps.

Hardware required:

2 MSP-US-TRF6901 (or MSP-EU-TRF6901) EVM kits

4 antennas (

See pg. 13 for how to choose an antenna

)

2 PCs each equipped with 1 serial port

2 Power Supplies

Setup Hardware:

Setup the 2 PCs wherever you want to demonstrate the RF link.

Assemble each ‘station’ according to the figure on

page 5

Review proper hardware and jumper setups in the EVM User’s Guide section 6.2.2.

Setup Software:

Download the file TRF6900 Demo_1_16.exe from the CD provided with the EVM kit
located under the following directory:
\MS-RF Chipset\Tools_Software\Setup_TRF6900 demo 1_16_Master

Install the software on each PC. See a snap-shot on

page 6

Establish a bi-directional link:

See

page 6

to start-up the software

See section 7.7.5 of the EVM User’s guide for more information on how to run the
software
